# Source summary — EmissionCadenceDeclaration draft

The King's Guard draft proposes a source-authored declaration that makes stream
silence observable. It distinguishes two forms:

- `expected-rate`: an event-class minimum over a time window;
- `heartbeat-or-reconciliation`: a positive liveness assertion, a comparison of
  source and observed counts, or both.

The draft was written against `qonto-assistant` and the Gate House approval
emission contract. It assigns evaluation to King's Guard and explicitly asks a
Taxonomy repository to own the schema.

Security-specific content associates event classes with `attributive` or
`load-bearing` evidence and requires the stronger form for rare, load-bearing
events. That policy is part of the source context, not the generic core adopted
by InfoTechCanon.
